Then, as shown by FIG. 1A and FIG. 1B, in conditions of closing the document cover unit 50, the compound apparatus 1A can read a manuscript through conveying the manuscript to the manuscript loading surface 41 by using the automatic manuscript conveying apparatus 53.

Then, in conditions of opening the document cover unit 50 as shown by FIG. 6A, a stopper wall 62 furnished in the document cover unit 50 and a stopper wall 63 furnished in the flat bed unit 40 are contacted as shown by FIG. 6B, consequently the rotation region of the document cover unit 50 is regulated within 90 degrees (from parallel to verticality with respect to the flat bed unit 40). Like this, in conditions of opening the document cover unit 50, the compound apparatus 1A becomes possible to load a manuscript on the manuscript loading surface 41.

<Rotation Operation of the Scanner Section 3>

Continuously, it is to explain about an operation that drives the scanner section 3 rotate with respect to the printer section 2 by referring to FIGS. 2A, 2B, 7A, 7B and 8.
